Bug Description

Worldguard doesn't prevent any interaction with sulfur cubes in protected regions for non-owner/members. You can hit cubes, place, extract and ignite blocks inside sulfur cube. Also WG doesn't cancel block damage from sulfur cube's tnt.

Explosion of cube's dymanite can destroy nearby blocks and trigger another tnt. Normal tnt, even triggered by sulfur cube's tnt, doesn't break any blocks.

Expected Behavior

Strangers (not owners and not members of protected region) can't interact with sulfur cube. Explosion of sulfur cube should not damage region's blocks.

Reproduction Steps

1. Enter someone's region.
2. Check that you can't place blocks inside region and "normal" tnt dropped from above doesn't harm region.
3. Go outside and spawn sulfur cube with Bucket of Sulfur Cube.
4. Push sulfur cube into protected region.
5. Place dirt into cube.
6. Push sulfur cube by hitting it.
7. Extract dirt from cube with Shears.
8. Place tnt into cube.
9. Ignine tnt with Flint and Steel.
10. Wait for explosion.

Update: I discovered that latest snapshot of WorldGuard (7.0.18-SNAPSHOT+f0239b63) prevents interaction (placing block in cube and extracting block from cube and ignition). Also, sulfur cube explosion can be prevented by other-explosion: deny flag.

But explosion damage from TNT isn't prevented by default like normal tnt or tnt minecarts, and another sulfur cubes from bucket can be spawned on top of existing one within protected region.
